Theres a new competitor in the Chromebook market: Dell. This morning, Dell unveiled its first Chrome OS notebook, the Chromebook 11. Dell says that the Chromebook 11 will last for 10 hours on a single battery charge, and that itll be fairly light at just 2.9 lbs. Those specs seem to give Dell a Chromebook thats on par with recent offerings from Acer and HP (HP, coincidentally, even has a quite similar notebook of its own called the Chromebook 11). But Dell plans to roll out even more Chromebook options over the next several months, which it says will target a broader audience of consumers as well as smaller businesses.
